INFLATION PEDAL PRESSURE LIMITER
MAINTENANCE
The inflation pedal pressure limiter helps prevent inflation
of standard size or larger tires or tubes beyond 60 PSI to
minimize risk of explosion. This device is for the safety of
the operator and bystanders. Proper operation of the
pressure limiter is essential to safe operation of the
machine. (See Fig. 17.9)
Check operation of the pressure limiter as follows at least
once a month:
1. Remove tires and/or wheels from the machine.
2. Connect the inflation hose to an empty service tank with
a pressure gauge (gauge should read 0). Use a
certified tank with at least 250 PSI pressure rating.
(See Fig. 17.10)
3. Depress inflation pedal to start air flow through the hose
and into the tank. Maintain a steady pressure for constant
flow.
4. Watch the rising pressure on the tank gauge and the
gauge on the machine. As tank pressure reaches 60 PSI,
the pressure limiter should stop the air flow automatically.
Both gauges should read 60 PSI ± 5 PSI.
5. If the pressure exceeds 60 PSI, adjust the knob on
the regulator by lifting the locking cover and turning
COUNTERCLOCKWISE. After adjustment is made,
secure cover in the locked position.
6. Repeat steps 1-6. Re-adjust if necessary.
7. After pressure limit has been set, check the manual
release valve function by pressing the button and releas-
ing pressure from the tank until it reaches 50 PSI.
Disconnect inflation hose, and release air inside tank.
(See Fig. 17.11)
THE PRESSURE LIMITER IS PRE-SET AT THE
FACTORY AND SHOULD NEED NO ADJUSTMENT.
ADJUST ONLY IF PRESSURE EXCEEDS 60 PSI.
Operating a tire changer with a defective, improperly
adjusted, or by-passed pressure limiter could result
in a tire explosion with severe injury or death to the
operator or bystanders. Always be sure that the
pressure limiter is operating properly on the machine
at all times. Pressure limiter is set at 60 PSI.
Any required inflation above 60 PSI should be
performed in an inflation chamber/safety cage. A tire
explosion may cause personal injury or death to
operator or bystanders.
